More flexible than the planar capacitors are lateral structures on and of thin
films. Propagating magnons can be injected and detected by narrow microwave
striplines [1]}, while Pt contacts on YIG films allow the study of
diffuse magnon transport by injecting them by the spin Hall effect or Ohmic
heating and detection in another contact by the emf generated by the inverse
spin Hall effect from spin pumping [2]}.
